Nominal data includes names or characteristics that contain two or more categories, and the categories have no inherent ordering. How can I combine nominal with ordinal data to build a unique variable? Some researchers call the first two scales of measurement (Ratio Scale and Interval Scale) quantitative because they measure things numerically, and call the last scale of measurement (Nominal Scale) qualitative because you count the number of things that have that quality. These types of values have a natural ordering while maintaining their class of values. But score the two possibilities 1 or 0 and everything is then perfectly quantitative.
